The invention has relation to creels on the orderof those whichare employed in various manufacturing processes for supporting bobbins, spools,- orthe'li-ke, loaded with supplies of rovings, yarns-and thelike, which are to .be operated upon, in convenient relations for the paying-out of the material that has been wound thereon. g p a p i i More particularly, the inventionhas rela tion to creels of the class in which the supply- 1b0bbins, spoolsyor the like,=are supported in 'pla'ce, conveniently for the delivery of their contents, by skewers or spindles mounted in upright positions with their lower ends or feet resting upon'suitable steps and with 1 their upper endsor tips-confinedby tip-re- ;tainers."

The invention provides in novel manner "for mounting and supporting skewer-supporting steps in their'proper workingrelations ii -connection with tubular and'other shell-like creel-rails of curvilinear or analogous cross-section. I, p I

inasmuch as the/invention has reference to only the steps bymeans of which bobbinsupporting skewers are mounted in connection with the longitudinally-extending bobbin supporting elements of a creel, and to the manner and means of supporting the steps in position in connection with the said longitudinally-extending elements, the drawings have been restricted to short portions of the lengths of two rails 1,1, and to steps and step-supporting means constituted by skewer-tip retaining devices applied to such portions. This extent of illustration will sufiice for inaking clear the following disclosure of the features and principles of the inven tion. The said two rails are supposed to be ones which are employed at intermediate heights in a creel. rail 1, 1, is shown equipped with a skewersupporting step 2, and with a skewer-tip-retainer 3. In practice, the rails extend in the direction of the length of the creel of which they constitute elements, and each thereof is equipped with a plurality of steps and with an associatedplurality of tip-retainers. In Fig. 1a bobbin 4, having a load or roving 5 wound thereon, is shown mounted upon a .or pintle stepped in the concavity of the top of a step 2 in connection with the lower rail,

the skewer and bobbin being maintained in upright position by means of tip-retainer 3 .,-1n connection with the upper rail, such tipretainer being nearly in vertical ahnement with the said step, and the opening of the eye of such retainer being occupiedby the skewer-tip. i a

The skewer-lip-retainer shown in Fig. l in connection with the lower rail is intended to serve in practice to confine the tip of a bobbin-skewer (not shown) that isstepped below such rail; the'step shown in connection with the upper rall is intended to receive the .5

foot or pintle of a bobbin-skewer that is restrained at its tip by a tip-retainer carried by a higher rail (or, other support) not shown. The number of rows or banks, one vabove another, of supply-bobbins provided for ini;;"--

a Preferably; the wire 31' is constituted by the stem of za..skewer-tip retainer 3. The con- It struction andformof-the retainer may vary somewhat in practice, although. the. particuti-psretainer shown in the drawings is preferred.

This tip-retainer comprises a wire of U or staple-form, which is combined with a rail 1 with the bend of the U projecting outward from the surface of the'said rail. The bend I stands out from the said surface, and the two legs of the U are spaced apart atlthe surf-ace of the rail'sufiiciently to provide an eye proportioned properly to contain a skewer-tip as in Fig. '1, as well as to permit suflicient play and free turning of the tip within such eye. Oneof: the legs is long and. constitutes the stem 31 of the top-retainer, the other leg beingshort; "The long leg orstem-31extends hor zontally,- diametrically acrossjthe tubula'r rail, such leg occupying holes in the shell or. wall of the rail at oppositesides of the latter andbeing made ,fast place by ri'veting at its extremity, .gThe portionof such extremity which occupies the corresponding hole in: the 'sai'dflshell or wall is reduced in diameter.

deringit difiicult of entry by a skewer-tip. As an obvious modification, the tip-retainer may be formed with two long legs, both eX- tending across the tubular rail and made fast as described above with reference to the long leg aforesaid, and both legs serving to support the step. By reason of the said legs L being spaced apart horizontally from each other between the points where they intersect the snrface of the rail, no obstruction is presented in the case of a skewer-tip laid against the convex surface of the lower portion of the rail, that is to say below the eye,

and pushed upward over such surface endwise into the eye. Thisoperatlon admits of being performed quickly. The surfaceof the rail guides the skewer-tip into the inner portion of the eye, so that, provided the said tip has been alined with the opening of the eye, and that lateral deviationfrom alinement is avoided, the introduction of the tip. into the eye takes place readily. The operation of mounting an associated bobbin and skewer in place 1n a creel iscapable of being performed by one hand holding the associ ated bobbin and skewer, without the assistance of the other hand, by operations involving placing the tip against the surface of the rail below a tip-retainer, sliding the tip upward upon said surfaceinto the opening of the eye of the tip-retainer, and dropping the foot of the skewer into theproperly-related step provided below. p

The principles and advantages of the in vention may be utilized through application 7 to creel-rails of other shell-like forms.
